Hi,

I have a BV7-40 mk6 with attached a PS3.

PS3 can exit sound either through HDMI (as PCM) or via optical cable (DTS, Dolby or AAC formats).

As I can configure both in BV7-40, I'm wondering which setup would be better choice. Currrently I'm passing just via HDMI to save one cable, but if the BV7-40 would make a better job getting plain DTS/Dolby signals, happy to switch.

Any idea or advices?

Hi There -- I just had a look at the user guide, and I would recommend using HDMI & configuring Linear.  This playstation configuration should decode the content locally & output lossless audio.  I think configuring the display's audio format to standard would let it handle up to 7.1 channels.

Hi,

The real answer is "it depends".

If you're looking for information about why you should do one or the other (or pros and cons of each), this posting might be interesting.

Cheers

Hi Geoff -- thanks for the link to the article.  It was very informative!  My peripherals are updated more often than my display or receiver, so their decoders are typically more up to date.

I hadn't considered the impact of post-processing differences between LPCM & CODEC signals.  Would this be something subjective requiring testing to find a preference?

Thanks a lot.

I went for HDMI option, in the light of a replacement of PS3 with PS4.
